Getting an Accurate Helical Pile Bid

Posted by EBS Geostructural on Oct 20, 2020 9:29:00 AM

Deep foundation pricing is multifaceted and a one price fits all approach can lead to unexpected costs. To break down the pricing, the following list can help provide a better understanding of the top 4 factors that can affect pile prices and why they are important pieces of information when looking for estimates:

Foundation Solutions for Environmentally Sensitive Areas

Posted by Intech Anchoring Systems on Sep 4, 2020 8:15:00 AM

A key benefit of helical piles is the ability to install them in environmentally sensitive areas. CHANCE helical piles are precisely engineered to create minimal disturbance to the soil itself during installation with the pitch and placement of the helices precisely calculated. Helical piles can also be installed using limited access installation equipment eliminating the need for damaging access roads and large equipment required for other foundation types.

Vertical and Battered Helical Pile Groups to Mobilize Lateral Load Capacity

Posted by Jason Herron, P.E., C.W.I. on Jul 9, 2020 8:15:00 AM

Helical piles have become a common piling system in the North American construction market.  They are used for many applications with low to moderate tension and compression loads.  Slender helical piles, less than 4.5 inches in diameter, have historically been used for light shear loads of 1 to 5 kips in vertical applications. This method derives the lateral capacity as a function of the pile’s allowable structural bending moment and the allowable passive earth pressure of the soil. It is common to analyze the capacity of the piles by theoretical slender pile equations, P-Y curves, or software programs that model P-Y response. An adequate safety factor or a service limit on the allowable deflection is applied to the allowable loads to determine an applicable pipe size. In recent years larger piles, with diameter greater than 5.5 inches, have been used for larger lateral loads.  Large diameter piles have been designed for loads in excess of 20 kips.
